Abstract
The utility model discloses an aerostat pressure control valve; a vertical frame (2) is arranged on a valve seat (1); a valve core (10) is connected with the vertical frame (2) by 2 to 4 gemels (8); a seal ring (9) is arranged on the valve seat (1). The utility model is also provided with a spring, a straight arm (6), and a crank arm (7); one end of the crank arm (7) is movably connected with the upright post (2); the other end is movably connected with one end of the straight arm (6); the other end of the straight arm (6) is connected with the valve core (10); one end of the spring (5) is arranged on the crank arm (7); and the other end is arranged on the vertical frame (2). The utility model has the advantages of light valve weight, convenient, easy and simple manufacture and assembling.
Description
Technical field
The utility model relates to the gas control and the fluid control valve field of aerostatics such as dirigible, balloon
Background technique
At present, aerostatics such as pressure type dirigible, balloon need the setting pressure control valve for preventing excessive superpressure, when gas pressure is too high, discharge the internal gas decompression.The valve that is used to control helium gas emission in the aerostatics is called the helium valve, and the valve that is used to control air discharging in the aerostatics is called air valve.Because the volume of aerostatics is bigger, and the atmospheric pressure difference of internal gas and external environment requires to be controlled in the slight pressure scope of (20～80) column, in order to discharge the gas of big flow, need effective leaving area of valve bigger, usually the exhaust plug diameter require 300 millimeters, 500 millimeters or more than, require in light weight, simple in structure simultaneously.Leakage rate was bigger when the valve in the common valve had butterfly valve to close, and flashboard valve weight is big, and plunger type valve flow is little, only is suitable for the small size valve.
The model utility content
The purpose of this utility model is exactly at the existing above-mentioned deficiency of aerostatics pressure controlled valve, and a kind of aerostatics pressure controlled valve is provided.
The utility model is made up of valve seat 1, stand 2, hinge 8, seal ring 9, spool 10; Stand 2 is installed on the valve seat 1, and spool 10 links to each other with stand 2 by 2-4 hinge 8, and seal ring 9 is installed on the valve seat 1.It also has spring 5, straight-arm 6, cranks arm 7, and crank arm 7 an end and stand 2 are movably connected, and an end of the other end and straight-arm 6 is movably connected, and the other end of straight-arm 6 links to each other with spool 10, and spring 5 one ends are installed in cranks arm on 7, and the other end is installed in the stand 2.It also has rocking arm 3, push-pull mechanism 4, and rocking arm 3 one ends and stand 2 are movably connected, and the pull bar of the other end and push-pull mechanism 4 is movably connected.
The utility model has the advantages that: valve is in light weight, makes easy to assembly simple easily.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
Embodiment
Stand is made up of the fitting seat and the cross bar of two symmetries, and stand is installed on the valve seat by bolt.Push-pull mechanism is the plug-type motor drive mechanism of straight line or directly makes push-pull mechanism with cylinder, also can be without push-pull mechanism, the gas pressure change of itself realizes closing valve and drives valve in the tube; rocking arm is a T-shape; the one end is movably connected by pivot pin and stand; the other end is movably connected by the pull bar of pivot pin and push-pull mechanism, and the curved bar end of T-shape rocking arm is provided with pushes scroll wheel.One end of cranking arm is movably connected by pivot pin and stand, and the other end is movably connected by an end of pivot pin and straight-arm, and the other end of straight-arm links to each other with spool, and spring is designed to the spring of adjustable spring, and on an end was installed in and cranks arm, the other end was installed in the stand.In order to guarantee the spool balance, hinge is made as three for best, becomes 120 degree uniform on same circumference.Spool links to each other with stand by hinge, and seal ring is installed on the valve seat.
Working principle: during the withdrawal of the pull bar of push-pull mechanism, the pulling rocking arm makes the scroll wheel of pushing of rocking arm depress and crank arm, and cranks arm to drive straight-arm and push the spool venting open.When the pull bar of push-pull mechanism is regained entirely, the push-pull mechanism outage, this moment, valve reached maximum opening, the valve opening state (see figure 1).When the pull bar of push-pull mechanism stretched out, the push-and-pull rocking arm moved upward, spring by crank arm, straight-arm acts on spool, makes spool close the valve motion.When the pull bar of push-pull mechanism stretched out entirely, valve was closed fully.During no push-pull mechanism, the gas pressure change of itself realizes closing valve and drives valve in the tube.
Claims (3)
1, a kind of aerostatics pressure controlled valve is characterized in that it is made up of valve seat (1), stand (2), hinge (8), seal ring (9), spool (10); Stand (2) is installed on the valve seat (1), and spool (10) links to each other with stand (2) by 2-4 hinge (8), and seal ring (9) is installed on the valve seat (1).
2, aerostatics pressure controlled valve according to claim 1, it is characterized in that it also has spring (5), straight-arm (6), crank arm (7), an end and the stand (2) of (7) of cranking arm is movably connected, one end of the other end and straight-arm (6) is movably connected, the other end of straight-arm (6) links to each other with spool (10), spring (5) one ends are installed on crank arm (7), and the other end is installed in the stand (2).
3, aerostatics pressure controlled valve according to claim 1 and 2 is characterized in that it also has rocking arm (3), push-pull mechanism (4), and rocking arm (3) one ends and stand (2) are movably connected, and the pull bar of the other end and push-pull mechanism (4) is movably connected.
